Are you skaters' accountant? Yuna's accountant? Mao's? How can you know who pay what? Trolling much? It's boring. You should visit skaters' social media, like twitter, instagram, to see how they are doing while touring aroud Japan. Besides, Japan has really many shows. Korea- only one. In terms of fans=money Japan is better for skaters. More shows, more money. But if they have a time window to visit Korea's shows, why not. They are doing their work. Don't see a problem.
Japan is really a magnet for skaters to go for competitions as well as for shows, with such supportive communities and fans! from the pics from the current SOI shows, i am happy for all skaters being able to tour with it post-season. and there are more shows to come during the summer.
